The ing a thumb-screw 36on the lower end thereof, and secured to the opposite end of the boltand on the upper side of the member 2a is a clamping member 37 adaptedto engage the frame portion of the piano. l/Vhen said member 37 isadjusted in position shown in heavy lines in Figure f the thumb-screwcan be tightened to rigidly hold the clamping member 37 against theframe portion of the piano, which will cause the piano to be rigidlysecured to the platform of which 2 is a part thereof.

The cross-rod 6 has flexible members and 41, such as belting or leatherstraps, secured thereto. These have snaps l2 and 43 on their free endswhich are adapted to be engaged in the eyes is and f5 in the extremeforward portion of the side members 21 and 22.

The method of operation of my device is as follows The platform 20, asabove described, is placed on the roller 18, and the arms 17 and 17 aresecured to the points 27 and 28. The belt members 40 and 4-1 are securedto said platform by the snap members s2 and 4.3. Let us suppose that thedevice is in the position shown in Figure 1. The awl 9 is released fromthe ratchet 6. The crank 11 is applied to the end of the shaft 6 andturned in a counter-clockwise direction. The weight of the rear portionof the piano will cause the rear portion of the device to traverse thepath shown by the dotted line'50 in Figure 1, and when the belting iscompletely unwound the piano will be in the position shown in Figure 2.The clamping means may now be released and the piano carried to anydesired point.

In the above described operation the porch 51 is supposed to benon-existent. In many cases it is desired to unload the piano directlyonto the porch. In devices of this nature heretofore known and used thishas been impossible. In my device the pins may be taken out of the holes29 and 30, the arms 1? and 17 may then be removed from the projections27 and 28. The crank 11 will be turned for a few revolutions and thebelting strips a0 and All will be unsnapped from the forward portion ofthe platform. The platform carrying the piano is now entirely free fromthe automobile and may be rolled on the rollers 26 and 31 onto the porchand to any desired-portion of the house of which the porch may be aportion thereof.

The method of unloading above described may be reversed for loading.

Having thus described my invention fully, what I desire to protect andsecure by Letters Patent is:

1. In a device of the class described, members secured to the rearportion of an automobile, roller means mounted in said memhere, aplatform having rollers on the lower side thereof and mounted on saidmembers, said platform adapted to receive and hold a piano fortransportation, and means mounted on the said members for moving theplatform from unloading position to transport position.

2. In a device for transporting pianos, members secured to each side ofthe rear portion of an automobile, said members having upwardlyprojecting members integral therewith, a roller mounted in the rearmostupwardly projecting member, a Windlass mounted in the foremost upwardlyprojecting member, arms projecting from said firstnamed members, aplatform equipped with rollers resting on the roller mounted in therear-most upwardly projecting members, said platform being connected tothe Windlass by flexible means, a member pivoted on the first namedmember and also pivoted to the rearmost portion of the platform.

3. In a device of the kind described, a rectangular frame secured to therear portion of a motor vehicle. a roller extending across the frame,downwardly extending arms secured to the rear portion of the frame, aWindlass secured in the front portion of the frame, a second frameadapted to rest normally on the first frame, pivoted arms secured to thesecond frame, and also secured to the downwardly extending arms securedto the first frame, flexible strips of material secured. at one end tothe Windlass and laving the other end secured to the second frame, thesecond frame being adapted to receive articles for transportation, andalso adapted to slide on the first mentioned frame.

In testimony that I claim the foregoing as my own I hereby aiiix mysignature this the 27th day of March 1925.
